automatic grouping (e.g. by Date if date is printed on document)
image correction (e.g. if image is upside-down)
able to scan more types of documents (e.g. pdf, png, ..)
I plan to run this on either a Windows 2016 Server or on a Windows 10 Pro system. For me, it isn't important if the application itself is accessible through a web interface or a client application. Being able to access the files on mobile by providing an endpoint to connect to is also a nice bonus to have.
I'm willing to pay a one-time price of up to 100$, ... free is better ofc.
